Gwyneth Paltrow threw on a skimpy red bikini during a trip to Porto Cervo Saturday. She was with her kids, Apple and Moses, and godfather Steven Spielberg and his wife Kate Capshaw for the Italian getaway. The group spent the day on the beach throwing a Frisbee, paddle-boarding, and swimming. Steven had his video camera out to capture the fun outing, and Kate toasted Gwyneth with a cold drink during lunch in the shade. Gwyneth was a little more covered up in a maxi dress when she, Steven, and Kate headed into town later that evening to shop with Apple and Moses. Yesterday the whole crew hung out on Steven's yacht and Gwyneth even took Moses for a spin on a jet-ski. Gwyneth's brother Jake also joined her for the family vacation, though her husband, Chris Martin, didn't attend since he was performing with Coldplay at a music festival in Scotland.
